  Thinks to think about before we meet:

  1) The Eml200DataSource uses the Ecogrid to get Metadata about an item and
then returns the data for that item as a single table. The QueryBuilder can
be used to reduce the number of columns that are pass through the ports, but
is not necessarily a require part of this data object.

  2) What else will we be using the generic QueryBuilder for? Meaning what
kind of data object will be returning more than one table that is not an
Ecogrid Query?
      2.1) I think we have talked about this when the user will be accessing
local data files; thru HSQL?  JDBC?
          2.1.1) If so, then how do they discover and get their local data
into Kepler?

  3) Do we need a more generic EcogridDataSource object that can execute
generic Ecogrid Queries? And if so, do we need an Ecogrid Query specific
QueryBuilder instead of a generic one?

  4) Do we need a DiGIR Data Source object, or would this be covered by #2.
If it was DiGIR specific than we could get data from node that may not be
register???? (I am not sure)

  Rod
